16 Operating mode DI 3.2 Parameters/address space 3.2 Parameters/address space High-speed inputs Function In operating mode DI, use all eight channels as digital high-speed inputs. High-speed inputs make sense when rapid reactions to input signals are needed (reaction time < 2 ms). Requirement Low reaction times require a cycle time of less than 750 µs Parameters The effective range of the parameters depends on the type of configuration. The following configurations are possible: Central operation with an S CPU Distributed operation on PROFINET IO in an ET 200SP system Distributed operation on PROFIBUS DP in an ET 200SP system In addition to configuration via the configuration software, you can also configure parameters in RUN mode (dynamic) via the user program. When assigning parameters in the user program, use the "WRREC" instruction to transfer the parameters to the module using the data records; refer to the section Parameter assignment and structure of parameter data record for DI operating mode (Page 66). 16 Manual, 03/2015, A5E AA

17 Operating mode DI 3.2 Parameters/address space The following parameter settings are possible for each operating mode: Table 3-1 Configurable parameters in DI operating mode Parameters Value range Default Configuration in RUN Potential group Use potential group of the left module Allow new potential group Use potential group of the left module Effective range with configuration software HSP0127 for STEP 7 (TIA Portal); HSP0229 for STEP 7; PROFINET IO GSD file PROFIBUS DP GSD file no Module Module Operating mode 1 DI / Oversampling no Module Module Diagnostics No supply voltage L+ Diagnostics Short-circuit to ground Counting Disable Enable Disable Enable Disable yes Module Module Disable yes Module Module Channel enabled Disable Enable yes Channel Channel Enable Input delay None 3.2 ms yes Channel Module ms 0.1 ms 0.4 ms 0.8 ms 1.6 ms 3.2 ms 12.8 ms 20 ms Pulse stretching None None yes Channel s 0.1 s 0.2 s 0.5 s 1 s 2 s Manual, 03/2015, A5E AA 17

If your PROFIBUS Master supports the "Read / write data record" function, you can set this parameter via data record If your PROFIBUS Master supports the "Read / write data record" function, you can set this parameter for each channel via data record Manual, 03/2015, A5E AA

19 Operating mode DI 3.2 Parameters/address space Explanation of parameters Potential group Specifies whether the a light BaseUnit with incoming voltage supply is located in this slot (see system manual ET 200SP Distributed I/O System ( Operating mode At the module level, specifies the operating mode in which the module's channels are operated: DI / Oversampling (Page 48) Counting (Page 28) When configuring with HSP0229 for STEP 7 or with a GSD file, the operating mode is specified by selecting the module name. Diagnostics: No supply voltage L+ Enabling of the diagnostics for no or insufficient supply voltage L+. Diagnostics: Short-circuit to ground Enabling of the diagnostics if a short-circuit of the actuator supply to ground occurs. Channel enabled Determines whether a channel is enabled or disabled. If a digital input is disabled, the module ignores its signals. Pulse stretching Pulse stretching is a function used to change a digital input signal. A pulse on a digital input is stretched to at least the configured length. If the input pulse is already longer than the configured length, the pulse is not changed. With Pulse stretching, you can reliably detect very short input signals without having to use a correspondingly short cycle time. In isochronous mode, the terminal signal is read in at the time Ti (time for reading the input data). In some cases, pulses that are shorter than the cycle time (send clock) are not detected. If you want to detect short signals isochronously, the Oversampling operating mode is recommended. Oversampling also provides more precise information about the time at which a signal occurs. Manual, 03/2015, A5E AA 19

20 Operating mode DI 3.2 Parameters/address space Principle of pulse stretching The figure below uses examples to show whether and how input pulses are changed. Figure 3-3 Principle of pulse stretching 20 Manual, 03/2015, A5E AA

21 Operating mode DI 3.2 Parameters/address space Input delay This parameter can be used to avoid signal faults. Changes to the signal are only detected if they are constantly pending longer than the set input delay time. Isochronous configuration is only possible if there is no input delay configured for at least one channel. In isochronous mode, the terminal signal is read in at the time Ti (time for reading the input data). The read time Ti refers to the channel for which no input delay time was configured. For input channels with longer input delays, the read time is moved accordingly. This means individual channels can be assigned input delays, if necessary, without having a negative impact on the possible cycle time. Note If you select the "None" or "0.05 ms" option for the input delay, you have to use shielded cables for connection of the digital inputs. Hardware interrupt: rising edge Specifies whether a hardware interrupt is generated for a rising edge. Hardware interrupt: falling edge Specifies whether a hardware interrupt is generated for a falling edge. Manual, 03/2015, A5E AA 21

22 Operating mode DI 3.2 Parameters/address space Address space Address space with value status (Quality Information, QI) The figure below shows the assignment of the address space with value status (Quality Information (QI)). "IB x" represents the start address of input byte x. The addresses for the value status are only available if the value status is enabled. Figure 3-4 Address space with value status Evaluating the value status An additional byte is allocated in the input address space if you enable the value status for the digital module. Bits 0 to 7 in this byte are each assigned to a channel. They provide information about the validity of the digital value. Bit = 1: No fault is present on the channel. Bit = 0: Channel is disabled or there is a fault/error on the module. If a fault/error occurs on a channel with this module, the value status for all channels is Manual, 03/2015, A5E AA

26 Operating mode DI 3.3 Interrupts/diagnostics alarms Interrupts The digital input module DI 8 24VDC HS supports hardware and diagnostic interrupts. Diagnostic interrupts The module generates a diagnostic interrupt at the following events: Channel temporarily unavailable Short-circuit Parameter assignment error No load voltage Hardware interrupt lost Evaluating hardware interrupts with IO controller The module generates a hardware interrupt at the following events: At rising edge (signal change from 0 to 1) At falling edge (signal change from 1 to 0) In the event of an interrupt, interrupt OBs are automatically executed in the CPU of the IO controller. You can obtain detailed information on the event in the hardware interrupt organization block with the instruction "RALARM" (read additional interrupt info) and in the STEP 7 online help. The channel of the module that triggered the hardware interrupt is entered in the start information of OB40 in the OB40_POINT_ADDR tag.

31 Counting operating mode (CNT) 4.2 Parameters/address space 4.2 Parameters/address space Counting Function Counting refers to the detection and summation of events. The respective counters of the module detect encoder signals and pulses and evaluate them accordingly, for example: For counting general piece goods up to a maximum limit For applications with recurring counting processes You can count with DI0 through DI3. You can specify each counter's characteristics using the functions described below. Counter limits The counting limits define the counter value range used. The counter limits are configurable and can be modified during runtime using the user program. The maximum possible counting limit is (2 31 1). The minimum possible counting limit is ( 2 31 ). You can continue or stop counting upon violation of a counting limit (automatic gate stop) Upon high and low limit violations of the counter value, an event bit is set in the feedback interface (Page 41) in each case. Start value You can configure a start value within the counter limits. The start value can be modified during runtime with the user program. Gate control Opening and closing the hardware gate and software gate defines the period of time during which the counting signals are recordd. The control of the hardware gate takes place externally via the digital inputs DI4 through DI7. The software gate is controlled via the user program. Use of the hardware gate can be enabled through parameter assignment. Count direction The counting direction is specified either via suitable external pulse signals at the each counter's control input or via the configuration. Manual, 03/2015, A5E AA 31

32 Counting operating mode (CNT) 4.2 Parameters/address space Comparison values You define two comparison values that can control the STS_DQ feedback bit, independent of the user program. If the current counter value meets the configured comparison condition, the STS_DQ reset bit is set. You can use the STS_DQ reset bit in order to control a digital output module's digital output. The comparison values are configurable and can be modified during runtime with the user program. When a comparison event occurs, in each case an event bit is set in the feedback interface (Page 41). 32 Manual, 03/2015, A5E AA

33 Counting operating mode (CNT) 4.2 Parameters/address space Parameters The effective range of the parameters depends on the type of configuration. The following configurations are possible: Central operation with an S CPU Distributed operation on PROFINET IO in an ET 200SP system Distributed operation on PROFIBUS DP in an ET 200SP system In addition to configuration via the configuration software, you can also configure parameters in RUN mode (dynamic) via the user program. When assigning parameters in the user program, use the "WRREC" instruction to transfer the parameters to the module using the data records; refer to the section Parameter assignment and structure of parameter data record for Counting operating mode (Page 70).

If a digital input is disabled, the module ignores its signals. Input delay This parameter can be used to avoid signal faults. Changes to the signal are only detected if they are constantly pending longer than the set input delay time. Isochronous configuration is only possible if there is an input delay of 0.05 ms configured for at least one channel. In isochronous mode, the feedback interface is updated at the time Ti (time for reading the input data). Note If you select the "0.05 ms" option for the input delay, you have to use shielded cables for connection of the digital inputs. Manual, 03/2015, A5E AA 35

36 Counting operating mode (CNT) 4.2 Parameters/address space Reaction to violation of a counting limit Selection of the reaction to violation of the counter high limit in the upward direction or the counter low limit in the downward direction: Stop counting: After a counting limit is violated, the internal gate is closed. This stops the counting process. The counter value is set to the opposite counting limit. To restart counting, you must close and reopen the software/hardware gate. Continue counting: After a counting limit is violated, the counter value is set to the opposite counting limit and counting continues. Edge selection Selects the edge that is counted: At rising edge: The respective counter counts all rising edges at the digital input. At falling edge: The respective counter counts all falling edges at the digital input. Note If the "Reverse direction" option is selected in "Set function of DI" and the counting direction in the process changes, the counting edge is automatically adjusted (opposite edges). Count direction Count direction selection: Up: The respective counter counts up. Down: The respective counter counts down. Note This parameter has no effect if the "Reverse direction" option is selected in "Set function of DI". 36 Manual, 03/2015, A5E AA

37 Counting operating mode (CNT) 4.2 Parameters/address space Set output Selects the function that controls the response of the STS_DQ feedback bit (Page 41): You can use the STS_DQ reset bit in order to control a digital output module's digital output. Off (DQ = 0): Regardless of the counter value, STS_DQ is permanently not set. Off (DQ = 1): Regardless of the counter value, STS_DQ is permanently set. Counter value between comparison value 0 and 1: STS_DQ is set if counter value comparison value 0 and counter value comparison value 1. Counter value not between comparison value 0 and 1: STS_DQ is set if counter value < comparison value 0 or counter value > comparison value 1. Setting function of the DI Selects the function of DIn+4, which controls the assigned counter input DIn: Digital input without function: No function is assigned to DIn+4. The signal status of DIn+4 can be read by the CPU using the feedback interface (Page 41). Gate start/stop: Setting DIn+4 opens the hardware gate for DIn. Resetting DIn+4 closes the hardware gate for DIn. Reverse direction: DIn+4 reverses the counting direction at DIn, in order to adjust it to the process. If DIn+4 is not set, DIn counts up. If DIn+4 is set, DIn counts down. Counter high limit Sets counter high limit. The following applies: Counter high limit > counter low limit Counter high limit (2 31-1) Counter low limit Sets the counter low limit. The following applies: Counter low limit < counter high limit Counter low limit (-2 31 ) Manual, 03/2015, A5E AA 37

38 Counting operating mode (CNT) 4.2 Parameters/address space Start value Sets the start value. The following applies: Start value counter low limit Start value counter high limit Comparison value 1 Sets the second comparison value. The following applies: Comparison value 1 > comparison value 0 Comparison value 1 counter high limit Comparison value 0 Sets the first comparison value. The following applies: Comparison value 0 < comparison value 1 Comparison value 0 counter low limit 38 Manual, 03/2015, A5E AA

39 Counting operating mode (CNT) 4.2 Parameters/address space Address space Assignment of the control interface Control interface The user program uses the control interface to influence the behavior of the module's counter. The figure below shows the address space allocation for the control interface in the process image of the outputs. "QB x" represents the start address of output byte x. Figure 4-3 Assignment of the control interface Manual, 03/2015, A5E AA 39

40 Counting operating mode (CNT) 4.2 Parameters/address space Notes on the control bits Control bit SLOT LD_SLOT SW_GATE RES_EVENT_UFLW RES_EVENT_OFLW RES_EVENT_CMP0 RES_EVENT_CMP1 Notes This value is used to specify the loaded value for each channel. Use the LD_SLOT load request to evaluate the loaded value. This load request is used to specify the meaning of the SLOT (loaded value) value for each channel. The user program performs the respective action, as soon as LD_SLOT changes. When the loading request LD_SLOT = 011B is entered and the software gate is opened, each counting operation begins with the start value. If another load request is entered and the software gate is opened, counting continues with the current count at each start of the counting operation. These two situations are also in effect when the hardware gate is configured and the software gate is closed. With this bit, you open and close the software gate of the respective channel. Together, the software gate and the hardware gate form the internal gate. The module only counts if the internal gate is open. 0 means: Software gate closed 1 means: Software gate open Use this bit to initiate the resetting of the saved event in the EVENT_UFLW feedback bit for the respective channel. Use this bit to initiate the resetting of the saved event in the EVENT_OFLW feedback bit for the respective channel. Use this bit to initiate the resetting of the saved event in the EVENT_CMP0 feedback bit for the respective channel. Use this bit to initiate the resetting of the saved event in the EVENT_CMP1 feedback bit for the respective channel. 40 Manual, 03/2015, A5E AA

41 Counting operating mode (CNT) 4.2 Parameters/address space Assignment of the feedback interface Feedback interface The user program receives current values and status information from the module via the feedback interface. The figure below shows the address space allocation for the feedback interface in the process image of the inputs. "IB x" represents the start address of input byte x. Figure 4-4 Assignment of the feedback interface Manual, 03/2015, A5E AA 41

42 Counting operating mode (CNT) 4.2 Parameters/address space Notes on the feedback bits Feedback bit STS_DIn COUNT_VALUE STS_DQ STS_GATE LD_STS_SLOT LD_ERROR Notes This bit indicates the status of the respective digital input DIn. This value returns the current counter value for the respective channel. This bit depends on the "Set output" parameter of the respective channel. You can use STS_DQ in each case, in order to control a digital output module's digital output. Together, the software gate and the hardware gate form the internal gate. This bit indicates the status of the internal gate for the respective channel. The module only counts if the internal gate is open. 0 means: Gate closed 1 means: Gate open Note: If you change a channel parameter in RUN mode via data record 128, all of the changed channel's values are retransferred to the module. In doing so, the internal gate of the respective channel is closed and the counter value is set to the start value. To restart counting, you need to close and reopen the software gate in each case. This bit indicates for the respective channel, by mean of a status change (toggling), that the load request for SLOT (LD_SLOT) has been detected and executed. This bit indicates for the respective channel that an error occurred (latching) during loading via the control interface. The loaded value was not applied. One of the following conditions has not been met: Counter low limit counter value (If this condition is not met, the start value is loaded as the current counter value.) Counter low limit start value Counter low limit comparison value 0/1 Counter high limit counter value (If this condition is not met, the start value is loaded as the current counter value.) Counter high limit start value Counter high limit comparison value 0/1 Counter low limit < counter high limit Comparison value 0 < comparison value 1 Do not write a reserved load request in LD_SLOT EVENT_UFLW EVENT_OFLW EVENT_CMP0 EVENT_CMP1 For the respective channel, this bit indicates the saved state which shows that there was a counter value underflow (a violation of the counter low limit). You reset the status by acknowledgment with RES_EVENT_UFLW. For the respective channel, this bit indicates the saved state which shows that there was a counter value overflow (a violation of the counter high limit). You reset the status by acknowledgment with RES_EVENT_OFLW. For the respective channel, this bit indicates the saved status which shows that a comparison event with comparison value 0 has occurred. You reset the status by acknowledgment with RES_EVENT_CMP0. The EVENT_CMP0 bit is not set when you set the counter value to the start value. For the respective channel, this bit indicates the saved status which shows that a comparison event with comparison value 1 has occurred. You reset the status by acknowledgment with RES_EVENT_CMP1. The EVENT_CMP1 bit is not set when you set the counter value to the start value. 42 Manual, 03/2015, A5E AA

43 Counting operating mode (CNT) 4.2 Parameters/address space Feedback bit RES_EVENT_UFLW_ACK RES_EVENT_OFLW_ACK RES_EVENT_CMP0_ACK RES_EVENT_CMP1_ACK Notes This bit indicates for the respective channel that the reset of event bit EVENT_UFLW is active. This bit indicates for the respective channel that the reset of event bit EVENT_OFLW is active. This bit indicates for the respective channel that the reset of event bit EVENT_CMP0 is active. This bit indicates for the respective channel that the reset of event bit EVENT_CMP1 is active. Complete acknowledgment principle Saving bits are acknowledged according to the complete acknowledgment principle. The figure below shows an example of the sequence of the complete acknowledgment principle in the event of an overflow: You then rest the control bit RES_EVENT_OFLW. 5 The RES_EVENT_OFLW_ACK feedback bit is reset. Figure 4-5 The EVENT_OFLW feedback bit is set as a saving event upon overflow. You set the RES_EVENT_OFLW control bit to trigger EVENT_OFLW reset. The RES_EVENT_OFLW_ACK feedback bit is set when reset of EVENT_OFLW is detected. Acknowledgment principle Note If you have initiated the reset of an event bit, you must wait for the respective feedback bit. Then you can initiate another reset. Note Opening the software gate or hardware gate (0-1 transition) resets all event bits. Manual, 03/2015, A5E AA 43

51 Oversampling (OVS) operating mode 5.2 Parameters/address space 5.2 Parameters/address space Oversampling Function Oversampling means detecting data in equidistant time subcycles. In doing so, the configured number of subcycles corresponds to one data cycle (send clock). Oversampling always makes sense when you need to detect data with a high time resolution but without wanting to use a very short data cycle. With the oversampling function, a send clock is divided into equidistant subcycles: Each subcycle detects an 8-bit value. A subcycle is at least μs in length. Subcycles are possible in steps from 2 to 32 (sampling rate). Requirement The interface module or CPU, with which the module is used, must support isochronous mode. Sampling interval The duration of a subcycle is the sampling interval. The cycle time T (send clock) for isochronous mode is specified in the configuration software. This time, divided by the configured sampling rate nsample, yields the sampling interval tsample of the module. Example calculation: Figure 5-3 Example of calculating the sampling interval Manual, 03/2015, A5E AA 51

52 Oversampling (OVS) operating mode 5.2 Parameters/address space Chronological sequence The figure below shows the chronological sequence for oversampling. The detected input data of a data cycle (send clock) is copied to the interface module in the next cycle data and are available to the CPU in the data cycle after the next one. n Subcycle Figure 5-4 Detected value from cycle n 8 bits apiece x 32 (max.) = max. 32 bytes of input data per data cycle Oversampling Note Do not use a reduction ratio for the send clock in this operating mode for blocks in your user program (for example, OB61). This will ensure that the processing of the data in the CPU's user program occurs in chronological coordination with the detection on the module. 52 Manual, 03/2015, A5E AA

53 Oversampling (OVS) operating mode 5.2 Parameters/address space Parameters In distributed mode, you can use the Oversampling operating mode on the PROFINET IO in an ET 200SP system. In addition to configuration via the configuration software, you can also configure parameters in RUN mode (dynamic) via the user program. When assigning parameters in the user program, use the "WRREC" instruction to transfer the parameters to the module using the data records; refer to the section Parameter assignment and structure of parameter data record for Oversampling operating mode (Page 75). The following parameter settings are possible: Table 5-1 Configurable parameters in the Oversampling operating mode Parameters Value range Default Configuration in RUN Effective range with configuration software HSP0127 for STEP 7 (TIA Portal); HSP0229 for STEP 7 Potential group Use potential group of the left module Allow new potential group Use potential group of the left module no Module Operating mode 1 DI / Oversampling no Module Counting Sampling rate 2 Values per cycle yes Module Diagnostics No supply voltage L+ Diagnostics Short-circuit to ground 3 Values per cycle Values per cycle Disable Enable Disable Enable Disable yes Module Disable yes Module Manual, 03/2015, A5E AA 53

DI (Page 13) / Oversampling Counting (Page 28) When configuring with HSP0229 for STEP 7, the operating mode is specified by selecting the module name. Sampling rate Specifies the number of subcycles per isochronous data cycle. Diagnostics: No supply voltage L+ Enabling of the diagnostics for no or insufficient supply voltage L+. Diagnostics: Short-circuit to ground Enabling of the diagnostics if a short-circuit of the actuator supply to ground occurs. Channel enabled Determines whether a channel is enabled or disabled. If a digital input is disabled, the module ignores its signals. Manual, 03/2015, A5E AA 55

56 Oversampling (OVS) operating mode 5.2 Parameters/address space Input delay This parameter can be used to avoid signal faults. Changes to the signal are only detected if they are constantly pending longer than the set input delay time. Isochronous configuration is only possible if there is no input delay configured for at least one channel. In isochronous mode, the terminal signal is read in at the time Ti (time for reading the input data). The read time Ti refers to the channel for which no input delay time was configured. For input channels with longer input delays, the read time is moved accordingly. This means individual channels can be assigned input delays, if necessary, without having a negative impact on the possible cycle time. Note If you select the "None" or "0.05 ms" option for the input delay, you have to use shielded cables for connection of the digital inputs. 56 Manual, 03/2015, A5E AA

57 Oversampling (OVS) operating mode 5.2 Parameters/address space Address space Address space The figure below shows the assignment of the address space. "IB x" represents the start address of input byte x. In the respective bit, the subcycles are counted from left to right. Up to 32 subcycles are possible. If fewer than 32 subcycles are configured, the bits that are consequently unused are set to 0. Figure 5-5 Address space for oversampling Note While you are changing parameters in RUN mode, corruption of input data can occur. Manual, 03/2015, A5E AA 57

The parameters set in STEP 7 are not changed in the CPU, which means that the parameters set in STEP 7 will be valid again after a restart. Note While you are changing parameters in RUN mode, corruption of input data can occur. Output parameter STATUS If errors occur when transferring parameters with the "WRREC" instruction, the module continues operation with the previous parameter assignment. The STATUS output parameter contains a corresponding error code. You can find a description of the "WRREC" instruction and the error codes in the STEP 7 online help. Manual, 03/2015, A5E AA 75
